I’m gonna split the cases and see what’s in there. Not sure if that junk was just from the one hour test ride I did, not noticing that boot being loose, or if this has been over time. If it was sucking in regular air, wouldn’t one expect more scoring in the cylinder? That chip is really the only thing. As far as the head goes, I could send with the cylinder or get another. I’m just gonna continue the tear down and see if these main bearings are crunchy or not.

Went ahead and did a conservative tally on a part out just in case

Things usually don’t pass through my hands to die, but at least I know I’m not in a hole (yet)

I’m also keeping a lookout for a parts bike in my area

Look on eBay for a used head.

Any chips or flakes on a cylinder wall equals replating.



This Yamaha 4JY-11111-01-00 HEAD, CYLINDER 1 fits the following models and components:

Yamaha Motorcycle 1999 YZ125L1 Cylinder Head

Yamaha Motorcycle 2000 YZ125 - YZ125M1 Cylinder Head

Yamaha Motorcycle 1998 YZ125 - YZ125K1 Cylinder Head

Yamaha Motorcycle 1994 YZ125F1 Cylinder Head

Yamaha Motorcycle 1995 YZ125 - YZ125G1 Cylinder Head

Thanks. I didn’t know 94 or 95 would work

Broke it down some more. Looks like an aftermarket basket. From the photo it looks like I might need plates. I do have a good pack sitting at the house. Right side bearing felt concrete from this side. Feeling optimistic, but I’m not forking over any cash until I know what I have. I was optimistic enough to buy some yamabond.

I would suggest some soap and water before working on a bike.

Any interest to post a VIN and engine number?

I know off the top of my head the model code is 5DH and the motor serial started with e101c or something. I remember checking the motor to make sure it was the same year as the bike

Cool. It is good to check all that.

I have seen a few people start buying parts, then later it turned out it was a different year than what they were told or thought.

I was lucky enough to learn that on the KDX.

Is there a picture in there? I don’t see anything

Never mind, quoted you and grabbed the link. Thanks for the heads up.

I posted a link. It came up as some small version of the actual ad, like a picture. I don't know how it did that.

Got the cases split today - fun stuff to come.

I ended up finishing this project last month. I just put a better rim on the back.

SHINY!!

Congratulations on getting it going!

Sweet! Great work.
